SECTION 1: GENERAL INFORMATION AND INSTRUCTIONS

Please Note the following:  All information relates to a ring-fenced electricity activity.  Financial information is to be stated in R’000 (For ex. R1 234 567,00 should be stated as 1 235).  RING-FENCED means that separate accounts are kept for the electricity activity. This should ensure that the revenues; costs; assets; liabilities; reserves and provisions are separately identifiable from those of any other business in the books of account of the local authority or other licensee.  It is essential that all aspects of every statement are completed.

 Returns to reach the NERSA before 1 March 2008 Copies of the NERSA Generation Information Forms are available on the NERSA web site www.nersa.org.za. Completed forms may be returned to one of the following addresses: e-mail: [email protected] post: P O Box 40343, Arcadia, 0007 facsimile: (012) 401 4700

Actual = latest financial year for which actual figures are available.

Budget = most recent budget and planned use of resources for the following financial year.

Own use = electrical energy used in the production process of the licensee.

Refer to Section 3 for capacity and energy definitions.

SECTION 3: FINANCIAL RESULTS PER POWER STATION BUSINESS UNIT Please complete one sheet per power station or licensed business unit and a consolidated sheet.

Financing costs (g) Redemption Interest (internal or external) Contributions to capital development funds

Allocated corporate overheads (h)

Net income (loss) (Tot.Revenue-Tot.Expenditure) Revenue = internal and external revenue derived from the production of electricity. The total revenue received should agree with the sales figures of Section 2 of FORM NER D2 where applicable.

Primary Energy Cost = Cost of Fuel and water used in the generation process. This includes the cost of electricity purchased for pumping at pumped storage power stations. Fixed costs are those that are largely independent of the stations output while variable costs vary with output.

Use of system cost = Cost charged to the power station by a transmitter or distributor for the use of their network for energy transfer.

Operations = Cost of operating salaries and allowances as well as operating stores and materials.

Maintenance = Cost of repairs and maintenance; including salaries, wages, allowances and payments to contractors.

Administrative / General = Cost of power station supervision, administration and local overheads.

Financing Costs = Capital charges such as capital redemption, interest and contributions to capital outlay.

Definition of costs used for performance indicators: Working costs = b+c+e+f Generation cost = a

SECTION 4: POWER STATION PRODUCTION STATISTICS AND PERFORMANCE INDICATORS

Please complete one sheet per operational power station / business unit Form NERSA G1 Page 5 of 7 Jan 08 Station name: …………………………… Maximum capacity: ……………….MW Actual 2007/08 Budget 2008/2009 Unused capacity (MW) ...... Time to return to service (months) ...... Net maximum capacity (MW) Net maximum power produced (MW) Energy sent out (MWh) Availability (%) Unit trips (number/year) Generation load factor (%) Efficiency (%) Staff employed (number) Energy Related Costs (R/MWh sent out)  Primary Energy ......  Working Costs (see def. in section 3) ...... Total Generation Cost (R/MWh sent out) Total Revenue (R/MWh sold)

Maximum capacity MW = the maximum (installed) sent out capacity that could be produced continuously with all installed plant running. (Unipede def of maximum electrical capacity). This is the capacity for which the power station should be licensed.

Unused capacity MW = capacity which are not operated for economic reasons and is excluded from the calculation of the performance of the power station.

Net maximum capacity MW = Maximum capacity minus unused capacity.

Net maximum power produced = maximum energy sent out by the total power station in any one hour.

Energy sent out MWh = the electrical energy that was produced by the power station after the deduction of the consumption of station auxiliary plant but includes the electricity used for own processes such as pumped storage pumping or own use of co-generators.

Availability = the energy that the available capacity of the station could have produced during the period, to the energy that the net maximum capacity could have produced during the same period. (Unipede def. of energy availability factor)

Unit trips per year = the average number of times that the generator breakers opened unplanned in the year per operating unit. (Unipede def. for “unplanned automatic grid separations per 7000 operating hours”)

Generation load factor = ratio of electrical energy produced over period divided by the electrical energy it would have produced at its net maximum capacity over the same period.

Efficiency = Electrical energy sent out by the power station divided by the primary energy used to produce the electricity. For coal gas fired stations this corresponds to the thermal efficiency. For pumped storage stations, this is the efficiency of the pumping/generating cycle.
